4. Benefits of AC PV Modules
Simpler Field Installation
MicroInverter is attached to the PV module in the factory
System design is simplified: Scalability
Increased AC Power Harvest
Increased Robustness – Longer Unattended Operation
Remote monitoring of individual components
Single failure does not affect others in the array
More Value-Add in the Factory
Less Assembly Work in the Field
5% to 20% more AC Power Harvest
